This guide for teachers, in English and Spanish, examines how assigned sex roles affect grade school girls in competitive sports, simple games, pastimes, and other extracurricular activities. A pre-test and post-test are included to measure the user's awareness of sexual stereotypes. Five object lessons cover the following topics: (1) myths that promote the exclusion of girls from sports; (2) assumed differences between "masculine" and "feminine" sports; (3) women who have distinguished themselves in sports; (4) different opportunities offered to boys and girls in sports and physical education; and (5) classroom alternatives that help stimulate interest and participation in sports among grade school girls.
